Synergy has upgraded to Android 4.1.2 while keeping all of our previous mods intact. This is a framework like no other. We essentially had to custom write a framework with pieces from the S3 4.1.1, the Note2 4.1.1, the S3 4.1.2, and the Note2 4.1.2. There’s even some other stuff found in no other frameworks at all. The kangers are gonna have a real hard time with this one :p

Among the most exciting features in this new build are:

1) An updated multiwindow. As of this moment, every other multiwindow out there is broken. The new multiwindow in this release of Synergy has been redone for 4.1.2 and includes new functionalities. Among these is a new floating keyboard. TrevE has more in the Verizon thread (post here: http://xdaforums.com/showpost.php?p=39389034&postcount=19173)

2) We at Synergy have written a new tool which optimizes memory leaks in all system apps. We ran before and after benchmarks on memory functions and saw a consistent improvement. In fact, the OS was able to cache even more apks in memory before Android dumped em. This process is something that none of us have ever seen before, and we’re really excited about it. Again, see Trev's post linked above for more details.

3) Sometimes apps and frameworks have bad strings of code that still function, but cause the CPU to waste cycles. We’ve gone through and validated the entire system to patch these errors and Synergy now officially runs cleaner than stock!

** Possible bug ** Just last night my phone was saying it was an hour later than it really was when on network time. I'm not near a timezone border so I know it wasn't a tower issue. However, none of my GSM testers reported this bug and none of the CDMA guys on the team saw it either. So I'm just putting this out there, careful when setting your alarms. Use user-forced time instead of network time if you're worried or have issues. Hopefully it was just me :)
